How do i generate collision blocks by tilemap position?

Hello everyone!

I'm using a tile map to create the graphical part of the levels on my game and i've been wondering if it's possible to make the game create collision blocks on every place where there's a tile by itself instead of me doing one by one.

Couldn't you just use the solid behaviour on your tilemap?

Or are you searching for a different solution?

Adding a second tilemap only for the collision should work..

I just realised that i could do that yesterday, sorry if the question was "dumb", and thank you for your help, i appreciate it!
